power puck question

[blowinsmoke]

How many of you are running a power puck with smarty? has anyone had trouble running it on 50 hp. mine runs fine on 90 but surges constantly on 50 (with smarty on 9, thats where it always stays) but i really need 50hp setting cause rail psi gets out of control quickly (27k +) before 3200rpm

On Saturday I just installed a power puck into my 06 3500 4x4 dually automatic. It runs great, and idles great both at 50 or 90 hp settings. I got it after much research. I wanted mpg improvement, not power. I am really happy so far. I know its early but so far my overhead is reading 19. 5 where before it always registered 14. 5... ..... and the overhead was always over by 2mpg over hand calc.



I have driven more hgwy than usual, but it is better. I always hand calc, and am waiting to hand calc 5 tanks to see my results. I play with the 90hp setting and I get pushed back in my seat! I am really impressed, and the 179 price can't be beat. Installation took under 10 minutes.
